Tube-type Cool Oil Unit

Pipe Type Cool Oil Cooler Utility Model Patent∶ZL 2014 2 0456485.0

One. Usage and Features∶

（1Purpose

Turbines, fans, coal millers, pumps, and marine propulsion systems in mining and industrial enterprises all require oil coolers for the lubrication of large and medium-sized machinery. Building upon the strengths of similar products, our company has conducted extensive experiments on the vibration of the oil-side laminar flow in the heat exchange tubes, successfully developing a new type of tubular oil cooler.

（2Product Structure and Working Principle

The tubular cooler operates with the oil flowing through the shell side and water through the tube side. The heat transfer coefficient on the oil side outside the tube is [insert coefficient value] times that of the inside tube side.120-10The thermal resistance is primarily on the oil side. This equipment replaces the traditional arch baffles with swirl guide vanes, with the main principle being that the cooling oil, after being pumped into the shell of the cooler, is guided by the swirl guide vanes to rotate and move forward. As it rotates, the oil also washes along the circumference of the tubes. The structural parameters of the tubes are the result of optimized selection through multiple comparative tests, offering excellent performance and safety for use, making it an ideal auxiliary equipment for steam turbine units.

（3Product Features

Tubular oil coolers have the following advantages compared to other types of oil coolers:∶

1. High thermal efficiency is a feature of the plate-type cooler.2-3Multiple

2.Tightly structured∶Its compactness is comparable to plate heat exchangers.1-2Multiple;

3.Low oil resistance due to the use of swirl baffles, with the oil entering in a tangential flow, which is favorable for fluid operation.

4.Long service life, easy installation and maintenance∶The heat exchanger tubes have minimal thermal expansion stress, thus preventing common issues like cracking and leakage. Additionally, the tube-shell structure allows for easy installation and maintenance.

3Selection Guidelines

Turbine models designed by domestic and international turbine manufacturers are diverse. Based on extensive data collection, our company has compiled various ordering and selection schemes for turbine oil coolers, as shown in the table. If customers have special usage requirements, please contact our company. V. Installation of the oil cooler∶

1Preparation before installation

Chilled oil cooler pre-delivery inspection0.6mpaWater pressure testing shall be conducted. However, prior to installation, the provisions of the "Technical Specifications for Construction and Acceptance of Electric Power Projects (Turbine Generator Set Volume)" should be followed.∶“Cool oil side should be worked under pressure1.5Double the hydrostatic test pressure, maintain.5Zero leakage for minutes.

2Coolant Cooler Installation∶

（1The cooler support is mounted on a pre-prepared bracket and can reliably meet its dynamic and static load requirements.

（2Due to the change from an arch-shaped baffle to a swirl guide plate on the support, the cold oil cooler's oil inlet direction is clockwise. Do not install it in reverse.
